BOOT'OR SHOE.

SPECIFICATION forming part of Letters Patent No. 548,427, dated October 22, 1895. Application iiled November 2, 1894:. Serial No. 527,693. (No model.)

.To a/Z whom it may concern.:

Be it known that I, WILLIAM C. COLLYER, of Reading, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Boots or Shoes, of which the following is a specification.

This invention has for its object to provide a boot or shoe sole capable of being used in diderent ways in the manufacture of boots and shoes and adapted to serve either as the inner sole of a McKay sewed boot or shoe or as the main sole of a turned shoe.

The invention consists in the hereinafterdescribed sole and in the hereinafterdescribed improvement in a boot or shoe, in which said sole forms a part.

In the accompanying drawings, forming a part of the specification, Figure l Vrepresents a perspective view of my improved sole. Fig. 2 represents a transverse section of the same. Fig. 3 represents a transverse section show.- ing the sole attached to the upper of a boot or shoe and constituting the inner soie thereof. Figa represents a vievsT similar to Fig. 3, showing the edges of the upper and the corresponding part of the sole flattened down preparatory to the attachment of the outer sole. Fig. 5 represents a view similar to Fig. 4, showing the outer sole in place and attached to the upper and inner sole. Fig. 6 represents a sectional view showing the first 'stage in the operation of making a turned shoe having my improved sole, the upper and sole being Wrong side out; and Fig. 7 represents a view of the construction shown in Fig. 6, the upper and sole being turned right side out` ln carrying out my invention I take two iiexible sole-shaped pieces a and a', of leather or other suitable material, of substantially the same size, thickness, and flexibility. I unite these 'pieces along a line substantially parallel with their edges and at such distance therefrom as to enable the marginal portion of each piece to constitute an independent tlexible lip, the said lips being lettered, re spectively, a3 and a4. I prefer to unite said pieces or layers by a line of stitches a2.

The solo constructed as described is adapted to be used either in the manufacture of McKay sewed or turned boots or shoes.

In making a McKay sewed shoe having my improved sole I bend back the lip a3 from the plane of the solo, as shown in Fig. 3, ai: a point close to the line of stitches c2, and thenl placing the edge of the upper c against said lip I unite the upper to the bent lip bya line of stitches a5, which are formed outside of the line of stitches u2 and extend substantially parallel with the plane of the sole-that is to say, the portions of the thread passing through the lip as and the upper are substantially pan allel with the plane of the sole, so that they resist to the best advantage any strain tending to separate the upper from the lip a3. I then. suitably trim oft thesurplus portions of the lip as and upper c and liatten down the remaining portions, as shown in Fig. et, after which I apply an outer sole h and connect the same with the upper and inner sole by stitches or other suitable fastenings Z22. It will be seen that the lip di entends in the plane of the compound sole across the line of upper-securing stitches and projects sufficiently to receive the stitches or fastenings b2, that secure the outer sole.

In the shoe shown in Fig. 7 the upper and sole are united in the same manner as in the shoes shown in Fig. 5, except that the upper is turned inside out, as shown in Fig. 6, while being stitched to thelip c3. When the upper is turned right side out, as shown in Fig. 7, the shoe is complete as a soft-soled shoe, the piece a constituting the outer sole.

It will be seen that the compound sole, constructed as described, may be furnished as an article of manufacture to shoe manufacturers for use in the different classes of Work above described, and that a boot or shoe having such sole, Whether made by one process or the other, constitutes a very flexible and durable article of footwear.

I claim-n 1. As an improvement in boots and shoes, a

compound sole composed of two flexible layers of substantially equal size and shape, united along a line substantially parallel with their edges and at a sufficient distance therefrom to form two independent flexible lips, either IOG of which is adapted to be bent outwardly from the plane of the sole, whereby one of said lips may be utilized to receive the stitches which attach the upper to the sole and the other as the .marginal portion of either an inner sole or an outer sole, as set forth.

2. A hoot or shoe having a compound sole composed of two layers united along a line substantially parallel with their edges and at a sufficient distance therefrom to kform two independent lips one of which is bent back from the plane of the sole and united to the upper by a line of stitches located outside-of the line of connection between the two layers and extending substantially parallel with the plane of the sole, the other lip being extended outwardly in the plane of the sole across the line of upperlsecuring stitches, asthemarginal portion of either an'inn er or' an outer sole. 3. A boot or shoe comprising1 a compound solecomposed of two flexible layers united along a line substantially parallel with their edges and at a sufficient distance therefrom to form two independent flexible lips, one of which is bent back from the plane of the Sole, an upper united to the bont lip by stitches located outside of the line of connection between the two layers and extending substan tially parallel with the plane of the Sole, the other lip extending outwardly in the plane of the sole across the line of upper-securing Stitches, and an outer sole attached to the upper and to the outwardly extending portion of the extended lip.'

In testimony whereof have signed my 'name to this specification, in the presence of,

two subscribing witnesses, this 27th day of October, A. D. 189i.

WILLIAM C. COLLYER. Witnesses:
